TONIGHT'S MUST-SEE II

The first week trimmed the college tournament from 68 teams to 16. Now two networks are enough.

CBS' doubleheader is in Washington, D.C., the only spot that has all four of its top-seeded teams. Marquette faces Miami at 7:15 p.m., with Indiana and Syracuse about 9:45.

TBS is in Los Angeles, with surprises. At 7:47 p.m., Ohio State- the only top seed in the region to survive - plays Arizona; at about 10:17, it's Wichita State and LaSalle, seeded ninth and 13th..

TONIGHT'S ALTERNATIVE

"Fall to Grace," 8 p.m., HBO.

Jim McGreevey was a typical politician, ambitious and intense. He had "the need to be adored, the need to be knighted," he says in this interesting documentary.

Then came the jolt: Comfortably elected New Jersey governor in 2002, he resigned midway in his term, admitting to an extramarital affair with the man he'd appointed the state's homeland security adviser.

And then? McGreevey, who had been a Catholic, spent three years in Episcopal seminary and began a prison ministry. It's an intriguing story, well-told. As usual, Alexandra Pelosi shows a knack for politics (her mom is House minority leader), filmmaking and humanity.

Other choices

? "American Idol," 8 p.m., Fox. A year ago, Colton Dixon seemed like a front-runner. He had the look of a hard-rocker and the passion of years of church music. But with seven people left, Dixon chose Lady Gaga's "Bad Romance" and finished last. The judges had already used their only save for Jessica Sanchez, so he was sent home. Now Dixon - who has a new album of religious music - sings tonight.

? "Community," 8 p.m., NBC. In a clever rerun, the group heads to the convention of a show a lot like "Doctor Who." Even the skeptics are involved: Pierce is in a focus group and a beauty (Tricia Helfer of "Battlestar Galactica") mistakes Jeff for one of the show's stars.
